This is because the time from the start of the stop operation to the completion of the stop operation (hereinafter referred to as required stop time) varies depending on the stop operation type, and the speed at which the temperature of the fuel cell system 310 decreases varies depending on the stop operation type. Specifically, since the cooling effect by the blower 153 or the radiator 156 cannot be expected in the shutdown, the stop time T2 accompanying the shutdown is longer than the stop time T1 accompanying the normal stop.

That is, the stop time T4 corresponding to the start state or the stop time T5 corresponding to the stop operation state is shorter than the stop time T3 corresponding to the power generation state.

  • the control unit 230 is No. in FIG. As shown in FIG. 4, the recommended time may be specified based on the abnormal part. This is because the temperature of the abnormal part at the time when the stop operation starts is different for each abnormal part. Specifically, the temperature of the cell stack 151B is the highest, and the temperature of the part is lower as the cell stack 151B is arranged at a position away from the cell stack 151B. For example, the control unit 230 specifies a time before the recommended time corresponding to the cell stack 151B as the recommended time corresponding to the hot water storage facility 160 or the remote controller.
